Patients with HIV-1 infection on HAART regimen including 2 NRTI/NtRTIs plus one of the following : 1 PI/ritonavir or ATV/unboosted or 1 NNRTI, will be randomized to switch from the NNRTI/PI to maraviroc (300 mg /12 h) or to continue with the same approach.

Patients with HIV-1 infection on HAART regimen including 2 NRTI/NtRTIs plus one of the following : 1 PI/ritonavir (lopinavir/ritonavir, atazanavir/ritonavir, fosamprenavir /ritonavir, tipranavir/ritonavir, darunavir/ritonavir) or ATV/unboosted (in a regimen without tenofovir) or 1 NNRTI (nevirapine or efavirenz).

Patients will be randomized to switch from the NNRTI/PI to maraviroc (300 mg /12 h) or to continue with the same approach.

The primary endpoint would be the percentage of patients who maintain virological suppression at week 48.
